What is Entity Salience?
Entity Salience measures how 'central' an entity is to a document, computed from frequency, position (first-paragraph weighting), and contextual co-occurrence. Google's NLP API outputs a salience score (0–1) — a core topical-relevance signal.
How do you apply it in practice?
Writing tip: have the core entity appear in the first paragraph, H1, and URL simultaneously, with 3–5 related entities co-occurring in the body.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Entity Salience" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.

Topical Authority
Topical Authority is Google's overall judgment of how comprehensively you cover a topic. The more complete the coverage, the tighter the internal links, and the higher the originality, the stronger the authority. It has overtaken single-page PageRank as a core ranking factor since 2024.
Semantic Search
Semantic Search returns results by understanding intent and context, not literal keyword matches. Google BERT (2018) and MUM (2019) were the watershed. Content implication: cover complete concepts and synonyms, never keyword-stuff.
